He had a few hits then people grew tired of him quickly
Few hits? Quickly? compared to who?
He had hit singles between 99-04. Even Blood in my Eye, which was Ja Rule's lowest selling album under Def-jam, produce a hit singles.(
It spawned one hit single, "Clap Back" which reached number 44 on the Billboard Hot 100 and had won him a Source Award for "Fat Tape" song of the year.)
Again, unless you're using the careers of a Jay'z as the standard for legendary status, I don't see any basis for your argument.
dont recall him having a classic album
Even if I grant you that(which I don't), I don't see how that is a necessary requirement. For example, Nelly, Ludacris, Busta, Fabolous, Cam'ron and etc don't have critically-acclaimed, classic albums, but I doubt that anyone would argue that they aren't legends. Because, determining one's legendary status is depended on a host of variables, not just one.
he is a b plus star kind of like Mase who is on my favorites all time but he wasn't in the game long enough
I don't see the comparison, Ja had 4 albums that went multi plat and produce multiple hits between 99-04. Mase was gone after Harlem world and never did anything of note after that point. You seem extremely misinformed about Ja's run.
